337037 - Firefox loads Google's "I'm Feeling Lucky" when using the middle mouse button to scroll

Status: RESOLVED DUPLICATE of bug 274773

(Firefox :: General, defect)

Description

[Simon Umbricht]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8) Gecko/20060428 Firefox/1.5
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8) Gecko/20060428 Firefox/1.5

Firefox [sometimes] loads a seemingly random page when scrolling down using the middle mouse button. The page loaded is always Google's "I'm Feeling Lucky" result for the last highlighted text section.

This is a very annoying behavior as it often draws my attention to some unsolicited page while reading something.

It' can't be an issue with any installed extension as I could reproduce this behavior without any extensions installed. I've tested it with Firefox 1.5 and 1.5.0.2 and the bug's present in both versions.

Reproducible: Sometimes

Steps to Reproduce:
1.open some page, preferably in English
2.highligth some word, preferably a common one
3.scroll down using middle mouse button. releasing the button after less than a second seems to favor this strange behavior

Actual Results:  
Loads unsolicited page after scrolling

Expected Results:  
Only scroll down

See Bug 274773 "Middle-clicking non-hyperlinked areas of a page attempts to 
load from clipboard"

There are several variants of this problem.

Thanks a lot, Ben!

The exact name of the property to change in about:config is middlemouse.contentLoadURL

In my eyes, this resolves this "bug", even though I can't understand why this feature has ever been implemented ...
